DETAILED DESCRIPTION

Before turning to the figures, which illustrate certain exemplaryembodiments in detail, it should be understood that the presentdisclosure is not limited to the details or methodology set forth in thedescription or illustrated in the figures. It should also be understoodthat the terminology used herein is for the purpose of description onlyand should not be regarded as limiting.

According to an exemplary embodiment, an energy storage and/orgeneration system for a refuse vehicle is disclosed herein. The energystorage and/or generation system of the present disclosure provides manyadvantages over conventional systems. The energy storage and/orgeneration system may be positioned to evenly distribute the weight ofbatteries across the frame of the refuse vehicle and/or minimizecomponent stress of one or more load bearing members (e.g., an axle) ofthe refuse vehicle. The energy storage and/or generation system may bepositioned to be easily accessible and/or removable from the refusevehicle. Ease of access and removability reduce the labor involved inservicing an energy storage and/or generation system, making routineinspection and servicing more feasible and thereby increasing the lifeof the energy storage and/or generation system. Furthermore,removability allows the energy storage and/or generation system to be“hot-swapped” when it is depleted of charge for a fresh battery, therebyenabling greater uptime for a refuse vehicle. In addition, a removableenergy storage and/or generation system may be safely charged at greaterspeeds than an energy storage and/or generation system confined to arefuse vehicle, thereby allowing for a smaller number of energy storageand/or generation systems to be used to support a fleet of refusevehicles. Finally, the energy storage and/or generation system may bemodular, allowing individual components of the energy storage and/orgeneration system to be easily replaced for one another. Modularity notonly reduces maintenance costs but also allows for future upgrades tothe energy storage and/or generation system. For example, the batteriesof the energy storage and/or generation system may be easily upgraded tofuture chemistries not yet available.

Overall Vehicle

As shown in FIG. 1, a vehicle, shown as refuse vehicle 10 (e.g., agarbage truck, a waste collection truck, a sanitation truck, a recyclingtruck, etc.), is configured as a front-loading refuse truck. In otherembodiments, the refuse vehicle 10 is configured as a side-loadingrefuse truck or a rear-loading refuse truck. In still other embodiments,the vehicle is another type of vehicle (e.g., a skid-loader, atelehandler, a plow truck, a boom lift, etc.). As shown in FIG. 1, therefuse vehicle 10 includes a chassis, shown as frame 12; a bodyassembly, shown as body 14, coupled to the frame 12 (e.g., at a rear endthereof, etc.); and a cab, shown as cab 16, coupled to the frame 12(e.g., at a front end thereof, etc.). The cab 16 may include variouscomponents to facilitate operation of the refuse vehicle 10 by anoperator (e.g., a seat, a steering wheel, actuator controls, a userinterface, switches, buttons, dials, etc.).

As shown in FIG. 1, the refuse vehicle 10 includes a prime mover, shownas electric motor 18, and an energy system, shown as energy storageand/or generation system 20. In other embodiments, the prime mover is orincludes an internal combustion engine. According to the exemplaryembodiment shown in FIG. 1, the electric motor 18 is coupled to theframe 12 at a position beneath the cab 16. The electric motor 18 isconfigured to provide power to a plurality of tractive elements, shownas wheels 22 (e.g., via a drive shaft, axles, etc.). In otherembodiments, the electric motor 18 is otherwise positioned and/or therefuse vehicle 10 includes a plurality of electric motors to facilitateindependently driving one or more of the wheels 22. In still otherembodiments, the electric motor 18 or a secondary electric motor iscoupled to and configured to drive a hydraulic system that powershydraulic actuators. According to the exemplary embodiment shown in FIG.1, the energy storage and/or generation system 20 is coupled to theframe 12 beneath the body 14. In other embodiments, the energy storageand/or generation system 20 is otherwise positioned (e.g., within atailgate of the refuse vehicle 10, beneath the cab 16, along the top ofthe body 14, within the body 14, etc.).

According to an exemplary embodiment, the energy storage and/orgeneration system 20 is configured to (a) receive, generate, and/orstore power and (b) provide electric power to (i) the electric motor 18to drive the wheels 22, (ii) electric actuators of the refuse vehicle 10to facilitate operation thereof (e.g., lift actuators, tailgateactuators, packer actuators, grabber actuators, etc.), and/or (iii)other electrically operated accessories of the refuse vehicle 10 (e.g.,displays, lights, etc.). The energy storage and/or generation system 20may include one or more rechargeable batteries (e.g., lithium-ionbatteries, nickel-metal hydride batteries, lithium-ion polymerbatteries, lead-acid batteries, nickel-cadmium batteries, etc.),capacitors, solar cells, generators, power buses, etc. In oneembodiment, the refuse vehicle 10 is a completely electric refusevehicle. In other embodiments, the refuse vehicle 10 includes aninternal combustion generator that utilizes one or more fuels (e.g.,gasoline, diesel, propane, natural gas, hydrogen, etc.) to generateelectricity to charge the energy storage and/or generation system 20,power the electric motor 18, power the electric actuators, and/or powerthe other electrically operated accessories (e.g., a hybrid refusevehicle, etc.). For example, the refuse vehicle 10 may have an internalcombustion engine augmented by the electric motor 18 to cooperativelyprovide power to the wheels 22. The energy storage and/or generationsystem 20 may thereby be charged via an on-board generator (e.g., aninternal combustion generator, a solar panel system, etc.), from anexternal power source (e.g., overhead power lines, mains power sourcethrough a charging input, etc.), and/or via a power regenerative brakingsystem, and provide power to the electrically operated systems of therefuse vehicle 10. In some embodiments, the energy storage and/orgeneration system 20 includes a heat management system (e.g., liquidcooling, heat exchanger, air cooling, etc.).

According to an exemplary embodiment, the refuse vehicle 10 isconfigured to transport refuse from various waste receptacles within amunicipality to a storage and/or processing facility (e.g., a landfill,an incineration facility, a recycling facility, etc.). As shown in FIG.1, the body 14 includes a plurality of panels, shown as panels 32, atailgate 34, and a cover 36. The panels 32, the tailgate 34, and thecover 36 define a collection chamber (e.g., hopper, etc.), shown asrefuse compartment 30. Loose refuse may be placed into the refusecompartment 30 where it may thereafter be compacted (e.g., by a packersystem, etc.). The refuse compartment 30 may provide temporary storagefor refuse during transport to a waste disposal site and/or a recyclingfacility. In some embodiments, at least a portion of the body 14 and therefuse compartment 30 extend above or in front of the cab 16. Accordingto the embodiment shown in FIG. 1, the body 14 and the refusecompartment 30 are positioned behind the cab 16. In some embodiments,the refuse compartment 30 includes a hopper volume and a storage volume.Refuse may be initially loaded into the hopper volume and thereaftercompacted into the storage volume. According to an exemplary embodiment,the hopper volume is positioned between the storage volume and the cab16 (e.g., refuse is loaded into a position of the refuse compartment 30behind the cab 16 and stored in a position further toward the rear ofthe refuse compartment 30, a front-loading refuse vehicle, aside-loading refuse vehicle, etc.). In other embodiments, the storagevolume is positioned between the hopper volume and the cab 16 (e.g., arear-loading refuse vehicle, etc.).

As shown in FIG. 1, the refuse vehicle 10 includes a liftmechanism/system (e.g., a front-loading lift assembly, etc.), shown aslift assembly 40, coupled to the front end of the body 14. In otherembodiments, the lift assembly 40 extends rearward of the body 14 (e.g.,a rear-loading refuse vehicle, etc.). In still other embodiments, thelift assembly 40 extends from a side of the body 14 (e.g., aside-loading refuse vehicle, etc.). As shown in FIG. 1, the liftassembly 40 is configured to engage a container (e.g., a residentialtrash receptacle, a commercial trash receptacle, a container having arobotic grabber arm, etc.), shown as refuse container 60. The liftassembly 40 may include various actuators (e.g., electric actuators,hydraulic actuators, pneumatic actuators, etc.) to facilitate engagingthe refuse container 60, lifting the refuse container 60, and tippingrefuse out of the refuse container 60 into the hopper volume of therefuse compartment 30 through an opening in the cover 36 or through thetailgate 34. The lift assembly 40 may thereafter return the empty refusecontainer 60 to the ground. According to an exemplary embodiment, adoor, shown as top door 38, is movably coupled along the cover 36 toseal the opening thereby preventing refuse from escaping the refusecompartment 30 (e.g., due to wind, bumps in the road, etc.).

Energy Storage and/or Generation System

As shown in FIG. 2, the energy storage and/or generation system 20 iscoupled to the rearward top portion of the body 14. In otherembodiments, the energy storage and/or generation system 20 is coupledto the forward top portion of the body 14. In some embodiments, theenergy storage and/or generation system 20 is removable/detachable fromthe body 14. Locating the energy storage and/or generation system 20 ontop of the body 14 facilitates easy access to the energy storage and/orgeneration system 20. For example, a user may readily inspect andservice the energy storage and/or generation system 20 because it islocated on an external surface of the refuse vehicle 10.

The energy storage and/or generation system 20 may include one or moreattachment mechanisms (e.g., pins, linkages, latches, etc.) to couplethe energy storage and/or generation system 20 to the body 14. In someembodiments, the energy storage and/or generation system 20 is a pod orbattery compartment, configured to receive and electrically couple oneor more batteries. For example, the energy storage and/or generationsystem 20 may allow a battery cell to be inserted from one end therebycoupling the battery cell to the energy storage and/or generation system20 and providing power to the refuse vehicle 10. In some embodiments,the energy storage and/or generation system 20 is modular andfacilitates easy replacement of one or more battery cells. For example,a second fully charged battery cell may replace a first depleted batterycell by uncoupling the first battery cell from the energy storage and/orgeneration system 20 and replacing it with the second battery cell. Insome embodiments, the entire energy storage and/or generation system 20is replaced with a different one of energy storage and/or generationsystem 20. Replacing one or more battery cells of the energy storageand/or generation system 20 reduces the downtime associated withcharging a typical battery system. In some embodiments, the energystorage and/or generation system 20 is “hot-swappable” and is able toreplace one or more battery cells without cutting power to the refusevehicle 10.

The energy storage and/or generation system 20 may include an electricconnection (e.g., a pantograph, a current collector, a high-voltageline, etc.) to allow the energy storage and/or generation system 20 toconnect to external power sources (e.g., an overhead power line, thegrid, a charging station, etc.). For example, the energy storage and/orgeneration system 20 may include a charging port to allow one or morebattery cells to be charged while the energy storage and/or generationsystem 20 is coupled to the refuse vehicle 10 (e.g., by a 220V charger).In some embodiments, the energy storage and/or generation system 20includes an electrical bypass to power the refuse vehicle 10 from acharging source while the battery is being charged. In some embodiments,the energy storage and/or generation system 20 connects to one or morepower sources of refuse vehicle 10 (e.g., an internal combustiongenerator, a battery, etc.) to charge the energy storage and/orgeneration system 20. For example, the energy storage and/or generationsystem 20 may include a connection to an onboard diesel generatorconfigured to provide power to the energy storage and/or generationsystem 20 for charging.

As shown in FIG. 3, the energy storage and/or generation system 20 iscoupled to the rearward bottom portion of the body 14. In otherembodiments, the energy storage and/or generation system 20 is coupledto the forward bottom portion of the body 14. As described above, theenergy storage and/or generation system 20 may be removable/replaceable.For example, the refuse vehicle 10 may include a door on the side of thebody 14 to allow removal and replacement of the energy storage and/orgeneration system 20. In some embodiments, the energy storage and/orgeneration system 20 is located on a track such that the energy storageand/or generation system 20 can slide out from the body 14 similar to adrawer. In some embodiments, the energy storage and/or generation system20 is modular. For example, the energy storage and/or generation system20 may include one or more sub-batteries to reduce the bulkiness of theenergy storage and/or generation system 20 and permit easy removaland/or replacement. Modularity further enables more precise inspectionand service of battery cells and allows individual battery cells to bereplaced without the need to replace an entire larger array.Furthermore, modularity enables battery cells to be easily upgraded.

As described above, the energy storage and/or generation system 20 mayinclude a charging port to allow the energy storage and/or generationsystem 20 to receive external power for charging. For example, therefuse vehicle 10 may include a 220V charging port on a side of the body14 to charge the energy storage and/or generation system 20.

As shown in FIG. 4, the energy storage and/or generation system 20 iscoupled between the cab 16 and the body 14. In some embodiments, theenergy storage and/or generation system 20 is coupled to the frame 12.Locating the energy storage and/or generation system 20 between the cab16 and the body 14 reduces a rear weight of the refuse vehicle 10,thereby reducing component stress of weight bearing members (e.g., arear axle). Furthermore, centrally locating the energy storage and/orgeneration system 20 protects the energy storage and/or generationsystem 20 from damage in the event of a collision. Furthermore,centrally locating the energy storage and/or generation system 20 allowseasy modification/retrofitting of existing refuse vehicles to includethe energy storage and/or generation system 20. The energy storageand/or generation system 20 may be easily accessed and/or removed fromthe refuse vehicle 10. For example, the energy storage and/or generationsystem 20 may include forklift pockets so that a forklift may easilyremove the energy storage and/or generation system 20 from the refusevehicle 10. In some embodiments, the system 20 includes one or moreeyelet connectors to receive a lifting hook or similar hoistingattachment. The energy storage and/or generation system 20 may beconfigured to connect to an external rail system to quickly replace theenergy storage and/or generation system 20 by sliding it orthogonallyoff the refuse vehicle 10.

In some embodiments, the energy storage and/or generation system 20 isconfigured to dynamically change position on the refuse vehicle 10 basedon loading of the refuse vehicle 10. For example, the energy storageand/or generation system 20 may translate horizontally along the frame12 toward the cab 16 or toward the body 14 to change a weightdistribution of the vehicle. In some embodiments, the energy storageand/or generation system 20 includes one or more controllers to measurethe weight distribution of the refuse vehicle 10 and adjust a positionof the energy storage and/or generation system 20 accordingly.

As shown in FIG. 5, the energy storage and/or generation system 20 iscoupled to the tailgate 34 of the refuse vehicle 10. In someembodiments, the energy storage and/or generation system 20 ispositioned vertically along a rearward side of the refuse compartment30. In some embodiments, the energy storage and/or generation system 20is positioned substantially near the base of the tailgate 34 or as partof the tailgate 34. The energy storage and/or generation system 20 maybe configured to be accessible via the tailgate 34. For example, a usercould open the tailgate 34 to reveal the energy storage and/orgeneration system 20. In some embodiments, the tailgate 34 includes oneor more rotating elements (e.g., hinges, mechanical bearings) tofacilitate rotation around a rearward corner of the refuse compartment30. For example, the tailgate 34 could include one or more hingingmechanisms on a side to allow a user to open the tailgate 34 like a doorand gain access to the energy storage and/or generation system 20located along the frame 12 of the refuse vehicle 10. In someembodiments, the tailgate 34 is a double door. Swinging the tailgate 34open like a door requires less energy than lifting the tailgate 34.

In some embodiments, the tailgate 34 is fully integrated with the energystorage and/or generation system 20 and is configured to beremovable/replaceable. For example, a first tailgate 34 having a firstenergy storage and/or generation system 20 could be replaced by a secondtailgate 34 having a second energy storage and/or generation system 20when the first energy storage and/or generation system 20 is depleted ofenergy. Removing and replacing the tailgate 34 may limit loss of vehicleoperation due to charging time because the tailgate 34 including thedepleted energy storage and/or generation system 20 may be chargedseparately of the refuse vehicle 10. Furthermore, swappable energystorage and/or generation systems enable a smaller fleet of refusevehicles to service the same area because the reduced downtimeassociated with battery charging enables the refuse vehicles to operatefor longer periods of time. In some embodiments, a number of racks indexone or more battery cells of the energy storage and/or generation system20.

As shown in FIG. 6, the energy storage and/or generation system 20 iscoupled between the body 14 and the frame 12. As described above, insome embodiments, the energy storage and/or generation system 20 may beconfigured to translate horizontally along the frame 12 of the refusevehicle 10. For example, the energy storage and/or generation system 20could move between a forward portion and a rearward portion of the body14 of the refuse vehicle 10 such that the refuse vehicle 10 is evenlyloaded. As described above, in some embodiments, the energy storageand/or generation system 20 is removable and/or replaceable. The energystorage and/or generation system 20 may be accessed via a door on a sideof the body 14 or via the tailgate 34. Similarly, the energy storageand/or generation system 20 may be removed and/or replaced by anotherenergy storage and/or generation system. Alternatively, one or moreindividual battery cells of the energy storage and/or generation system20 could be replaced. In some embodiments, the energy storage and/orgeneration system 20 can be accessed by removing the refuse compartment30. For example, a refuse vehicle with a removable refuse compartment(e.g., a container truck) may remove the refuse compartment to revealthe energy storage and/or generation system 20. In some embodiments, theenergy storage and/or generation system 20 is coupled to the refusecompartment 30 itself and can be removed with the refuse compartment 30.For example, a refuse vehicle could swap a first full refuse compartmentwith a first depleted energy storage and/or generation system for asecond empty refuse compartment with a second charged energy storageand/or generation system.

Referring now to FIGS. 7A-8B, several illustrations of an exemplaryplacement of the energy storage and/or generation system 20 is shown,according to several exemplary embodiments. In various embodiments, theenergy storage and/or generation system 20 is coupled to a rearward topportion of the refuse vehicle 10 (e.g., above the refuse compartment 30,etc.). Additionally or alternatively, the energy storage and/orgeneration system 20 is coupled to a rearward portion of the refusevehicle 10. For example, the energy storage and/or generation system 20may be coupled to the tailgate 34 and/or a rearward portion of therefuse compartment 30 (e.g., as shown in FIGS. 7A-7C). As anotherexample, the energy storage and/or generation system 20 may be coupledto a vertical rear surface of the refuse compartment 30. In someembodiments, the energy storage and/or generation system 20 orcomponents thereof are coupled to the wheel 22. For example, an energystorage cell of the energy storage and/or generation system 20 may becoupled to a hub of the wheels 22 and a power converter of the energystorage and/or generation system 20 may be coupled to a top rearwardportion of the refuse container 30. In some embodiments, the energystorage and/or generation system 20 is coupled to a front and rearwheelset of the refuse vehicle 10 (e.g., as shown in FIGS. 7A-7C). Invarious embodiments, placement of the energy storage and/or generationsystem 20 as shown in FIGS. 7A-7C facilitates shifting weight rearwardon the refuse vehicle 10, thereby reducing strain on forward loadbearing components (e.g., a front axle, etc.). In some embodiments, theplacement of the energy storage and/or generation system 20 shown inFIGS. 7A-7C is preferred for a rear-loading refuse vehicle 10. Invarious embodiments, the energy storage and/or generation system 20includes a different number and/or arrangement of components than shownexplicitly in the FIGURES. For example, the energy storage and/orgeneration system 20 may include a first component coupled to anexterior hub surface of the front wheels 22 electrically coupled to asecond component integrated with the tailgate 34. In some embodiments,the placement of the energy storage and/or generation system 20 shown inFIGS. 8A-8B is preferred for a front-loading refuse vehicle 10 and/or aside-loading refuse vehicle 10. In various embodiments, the energystorage and/or generation system 20, or components thereof, aredetachable from the refuse vehicle 10 as described in detail above.

Referring now to FIGS. 9A-9B, several illustrations of another exemplaryplacement of the energy storage and/or generation system 20 is shown,according to several exemplary embodiments. In various embodiments, theenergy storage and/or generation system 20 is coupled to a top portionof the refuse vehicle 10. For example, the energy storage and/orgeneration system 20 may be coupled to a top portion of refusecompartment 30 and/or above the cab 16 (e.g., as shown in FIGS. 9A-9B).In some embodiments, the energy storage and/or generation system 20 iscoupled to a canopy (or other structural element) located above the cab16. Additionally or alternatively, the energy storage and/or generationsystem 20, or components thereof, may be coupled to the wheels 22. Forexample, a first component of the energy storage and/or generationsystem 20 (e.g., a battery cell, etc.) may be coupled to an exterior hubregion of the wheels 22 and a second component of the energy storageand/or generation system 20 (e.g., a power converter, etc.) may becoupled to a structural element (e.g., a portion of frame 12, etc.)above the cab 16. In some embodiments, the placement of the energystorage and/or generation system 20 shown in FIGS. 9A-9B is preferredfor a rear-loading refuse vehicle 10. In various embodiments, theplacement of the energy storage and/or generation system 20 as shown inFIGS. 9A-9B facilitates moving weight (e.g., battery weight, etc.)forward on the refuse vehicle 10 (e.g., toward the cab 16 and away fromthe tailgate 34, etc.), thereby reducing stress on rear load-bearingcomponents (e.g., a rear axle, etc.).
